Some bunnies have a misalignment of their upper and lower teeth. Normally the side to side motion of eating hay will wear uppers against the lowers and vice versa. However, when the teeth do not align properly due to genetics or an injury, the teeth do not meet correctly and they do do not wear down properly, leaving high areas or spurs/points.
My Raven was a dwarf and over time one side of his molars would wear almost to his gums, yet very sharp points would form where his teeth did not wear and if allowed to grow the spurs would injure his tongue or cheek. His teeth misalignment got worse over time until he needed monthly dentals.
My vet did have to adjust his GA drugs because he was sensitive to one of the sedation meds. Once that was done he ate some greens right after his procedure.
Like others on this forum, I purchased different varieties of hay to encourage him to eat it, He ate the softer varieties/cuttings better. However, his teeth wore unevenly so he still needed dentals to remove the points that were rubbing on his cheeks and tongue.
He would pick up hay and take a few nibbles before stopping, so he wanted to eat, yet it was hurting him. He would not even eat hard pellets, so I let him eat his favorite greens and gave critical care until he was healed after his burring to keep him from losing more weight and going into stasis which he had several times.
He got accustomed to hands on care and regular vet visits. He bonded to me due to all the meds and syringe feeds.
Initially he got Medicam for pain to keep him eating when he was close to needing a dental.
Forgive me for the long post. I wanted to share my experience with a special dental bunny.
Sending you and your bunny vibes that you will be able to find a way to balance her vet visits and thr stress.
